At 02.10 hours on 7 March 1943, U-230 attacked the convoy SC-121 south-southeast of Cape Farewell and torpedoed the Egyptian (Master Dominic Vincent Murphy). Siegmann thought that his victim sank and attacked the convoy again at 09.25 hours. He claimed the sinking of another ship with 5000 tons in the former position of the Egyptian, but it seems that both attacks were carried out on the same ship.
The Empire Impala was ordered to pick up the survivors, dropped behind the convoy and was sunk with all hands by U-591 (Zetzsche) at 09.06 hours.

The master, 36 crew members and nine gunners from Egyptian were lost. Three crew members were picked up by HMCS Rosthern (K 169) (Lt R.J.G. Johnson, RCNVR) and landed at Londonderry.
